-/* This piece of code is heavily based on the original version of run-parts,
- * taken from debian-utils. I've only removed the long options and a the
- * report mode. As the original run-parts support only long options, I've
- * broken compatibility because the BusyBox policy doesn't allow them.
- * The supported options are:
- * -t test. Print the name of the files to be executed, without
- * execute them.
- * -a ARG argument. Pass ARG as an argument the program executed. It can
- * be repeated to pass multiple arguments.
- * -u MASK umask. Set the umask of the program executed to MASK.
